Speccation of Letters Patent.

Patented Sept. 1ML, 1915.

Application le'd April 25, 1914. Serial N o. 834,464.

To all whom t may concern:

Be it known that I, EDWIN GUsTAFsoN, a subject of the King of Sweden, residing at Chicago, in the county of Cool: and State of Illinios, have invented certain new and useful Improvements in Metal Doors, of which the following is a specification.

My invention relates to sheet metal door and window frame construction.

One of the general objects of myinvention is to provide a new and improved hollow rectangular frame, suitable for sheet metal doors, or windows, having a rect-angularcross section and preferably presenting substantially continuous, longitudinal, inwardly-facing slots, in each of the members, wherein to insert the attaching means for holding the molding and retaining the panels, of metal or glass, in place, without providing other openings in the structure for the introduction of such parts.

Another and more Specific object of my invention is to provide means for joining the mitered ends of the molding, to hold relative parts thereof in common planes, so as to prevent them from tilting, or cooking up at their edges. And still another object I have 1n view is to provide convenient' means for adjustably moving the panel and molding locking strips by means projecting through the body part or frame of the door, whereby the parts to be assembled, within the frame of the. structure, may be taken out and replaced by a novice without the necessity of inserting a special tool within the frame, or providing' an additional opening to be subsequently closed, for accomplishing this result.

Other. further and more specific objects of my invention will become readily apparent to persons skilled in the art, from al consideration of the following description when taken in conjunction with the vdra wings. wherein- Figure l is an elevation of a door, or sash. Fig. 2 is a transverse section. taken on line of Fig. 1, Fig. is a transverse section. taken on line 3 of Fig. l. Fig. 4 is a section taken on line l-l of Fig. 3. Fig. 5 is a transverse section, similar to Fig. 3, of a modified form of construction. FigZ 6 is a similar' view of another modified form of construction. Fig. 7 is a sectional view taken on line 'i' 7 of Fig. Fig. S is a sectional view taken on line 8 8 of Fig'. 6.

Fig. 9 is a section taken on line 9-9 of Fig. 1. Fig. l0 is a perspective View of a broken away corner of the frame. Fig. 11 is an elevation showing the manner of joining the molding members at a mitered corner. 6C

forming one of the members for locking same in place within the frame.

In all the vie-ws the same reference characters are employed to indicate similar parts.

The Stiles 'l5- l5 and the end rails 16-16 70 are substantially of the same cross section, each being provided with a wall l5a and two side walls 15*15b. One form of the structure shown in Fig. 5 contains only these three walls and this is especially true where the beading extends laterally beyond the walls 15b as in Fig. face of the molding comes substantially flush with the walls 15b, the end wall l5 is outwardly deflected, as at 15d to provide 80 a shoulder or rest for the molding as clearly shown in Figs. 2, 3, and 10, while in Fig. 6, in which the molding is applied only on one side of the frame, one of the walls 15b, eX-

tends forwardly, as at 15e, and bends back 85 upon itself to form a channel for a. locking strip, as at lf, as will be hereinafter more fully described. The stiles 15-15 and the end rails lG-l are mitered together, as at 1T. Inner plates 18 and 19 may be provided 90 for this purpose, the walls being preferably -spot welded to these plates, in initially putting the frame members together.

The space or channel, between the confronting wall portions 15d-15d preferably 95 -extends longitudinally of the respective members, and provides an opening through which reinforcements may be inserted for the purpose of attaching the necessary hardware to the frame, such as the lock, hinges and the like.

Locking strips 20, 20a and 20b,'as the case may be, extend for a considerable length of each of the members 15 and 1G and in each case the locking strips are adapted to tit neatly within the longitudinal openings provided in confronting side walls of said frame structure.

rThe locking strips 20, 20a as shown. are

channel shaped, each having a vertical por- 13G There the outer surp sides bent in the same direction as the other ported by the frame.

form of strip, but its other side is bent in the opposite direction, as at 15, resembling a Z-shape instead of a U-shape and lies between the wall 15@ and 15f, as shown in Fig. 6. Each of the locking strips is provided, at selected intervals with slots, or perforations 21, in their side members.

A panel 22, which may be either glass,

or other suitable material, is to be placed.

within the area surrounded by the frame, and held therein by means of molding strips 23, which may be placed on either or both sides of said panel. The molding strip frame being co-extensive with the inner opening of the frame adapted to be sup- The strips may be made of a front wall 2st bent into an o'gee mold with a beading 25, and a rear wall 26, and another beading 27 at its outer marginal edge. The bead 25 is again bent upon itself, as at 28, preferably to form a surface that may rest upon the shoulder provided by the wall 15d of the frame member. Adjacent strips of molding 23-23 are mitered at their edges, as at 23a-23a to make a joint between said molding pieces, corresponding with the preferably mitered ljoints between the end and side members of the frame. To prevent tilting, or cooking up,of the molding members thus joined, I prefer to employ Aan angle'piece 29, made of sheet metal, which fits snugly ivithin the interior of the hollow molding members, being bent or de lected in its miter plane in such manner as to hold the parts of the molding, at the joint, in perfect alinement, thus preventing any relative displacement thereof. The angle piece 29 may be spot welded, or other# wise secured to either of the molding members 23, or to both, if desired. It will, however, perform its necessary and required function without being positively united or connected to either of the molding members. The angle piece 29 lits tightly in the corners provided between the walls 26 alid QT, and the diagonal corners provided by the bead 25 of the molding, and the parts 29-QSV are so bent or deflected with reference to each other as to conform to the proper angularity of the molded pieces. locking clip 30 of which there may be any desired number are in like manner placed within the hollow portion of the molding in generally the same situation. They are each adjustable. longitudinally of the molding, so as to be brought to register with the openings 31 provided in the wall-members 15d-45d. of the stiles 1515 and the end vided with a locking lug 30 that is preferi ably punched from the body portion of the strip and bent at right angles as clearly shown in Fig. 13 and it is this locking lug that must register with the opening 31 provided in the frame member. The clips 30, may be moved along the interior of the molding to the selected position until they will freely enter the openings referred to,

at which time they will project through similar openings 21 made at equal intervals placed in the molding strips 23.

Secured at one end, to each ofthe locking strips 20-20a--20b is a strip extension 32, fastened to said strip by riveting, welding, or the like, as at 33. Each strip 32, is twisted a quarter turn, as at 34, so that these strips may pass each other to be conveniently separated and independently adjusted wit-hout relative interference. Each of the strips is bent at its end at an angle, as at 35, the bent end being perforated and threaded for an adjusting screw 36, which passes through the wall of one of the frame members, as shown clearly at 37, in Fig. 1. lVhen the screw 36 is rotated it causes the locking strip to be drawn toward the outer wall of the frame member, in the process of locking the molding strip to the frame member thereby securing the molding frame and panel in properpositions. l

To assemble the parts in the frame, composed of the members 15 and 16 it will be understood that the frame is first made complete, the joining ends of the frame members being vsuitably connected together, as by welding, or otherwise, and by the use of a mitered or square joint, as best suited for the purpose.

After the Jtrame has been completed the inserts, necessary for attachment of the required hardware to the frame, such as locks, hinges and the like may be passed through the channel openings made in the side walls 15c of the frame, after which the locking strips 20 are placed in the openings, which substantially closes the openings. The locking strips are moved longitudinally of the frame members until the slots 21 of the locking strips register with the slots 31 made in the portion 15d of the side wall 15C of said members. There may be as many of these registering openings in the respective members as may be desired for properly holding the molding in place. The locking clips 3() are then placed inside of the molding strips Q3 so that the tongues 30 thereof,

Lisette should be moved in said molding strip, un- A.

til they occupy positions registering -With the-slots 21 and -31 of the respective locking strips and frame members, so that the tongues 30 may be easily passed through said perforations when the molding strips are placed in position.. Before placing the molding strips 23 within the frame, the respective strips are relatively placed so that their adjoining ends produce a proper miter joint, as shown in Fig. 10, and so that the angular piece 294-29 will enter each' of the adjacent molding strips -just as the locking clips 30-is securedwithin such strips.

The inner frame, which is made byl the joining of the respective molding members, 1s placed within the main frame on one or both sides of the panel so that the locking tongues 30A of the clips 30 will pass through the registering slots or openings, heretofore referred to, and the locking strip extensions 32 are extended toward the respective walls of the frame. The bent portion 35 on the end of the extension 32 is provided with a screw threaded hole and a screw 36, inserted through theiopening 3'? in the frame must be entered in this hole. l v

To lock the molding'frame in place the screw 36 is turned, thus drawing the locking strip longitudinally so that the perforations 21 of the strip no longer register with the perforations 31, as shown in Fig. 4, and the body portion of the locking strip, beyond said perforations passes under the tongues 30 of the locking clip 30, thereby wedging the parts together and preventing removal of the panel and molding. g

After the moldinghas thus been applied to one side of the frame, the panel 22 is then placed on the surfaces or shoulders 26,.of the molding, and the molding frame on the opposite side 'of the panel is placed in position in a similar manner, the screws 36 being turned until the molding on each side of the panel is securely fastened to the main frame.

rI he strips 23 off the molding frame may be removed from the main fram-e by turning the screws 36 in the opposite direction and by driving on the end of the screws thereby longitudinally moving the locking strip back into its former position of registration of slots 21 with the slots 31 in the frame member, at which time the molding frame may be lifted from its place and the panel 22 removed.

While I have herein shown a single embodiment of my invention for the purpose of clear disclosure it is evident that considerable changes may be made in the relative positions and conguration of the parts within the meaning of the appended claims.

Having described my invention, what I claim is l. A device of the character described comprising a hollow, rectangular frame; a panel for inclusion therein; molding strips overlying said panel carrying lugs; longitudinally movable locking strips provided with coacting locking members within said frame; and scr'ews taking through the edge walls of the frame and engaging said strips to longitudinally move them into locking position tohold the molding and panel in place.

2. A device of the characterdescribed comprising a hollow, rectangular frame, provided with slots in its inner edge; a panelv for inclusion within said frame; molding strips overlying said panel; longitudinally adjustable lugs within said molding strips; longitudinally movable strips provided with slots coacting and registering with slots within said frame; and screws taking through the outer edge walls of the frame and engaging said strips to move them into locking engagement with said lugs and out of register with the slots in said frame.

3. A device of the character described comprising a hollow, rectangular frame provided with a substantially continuous opening in its confronting walls and having transverse slots in its walls near said opening; longitudinally movable strips substantially closing said opening having registering slots in its walls; a molding frame provided with tongues projecting through said openings and means movable from the outside of said frame to move the strips to engage said tongues and lock the" molding frame.`

4. In a device of the character described, the combination of a hollow, rectangular frame providing a shoulder for seating a molding by deflecting part of its inner wall inwardly, and having slots through the Walls of the shoulder parts; a molding seated on said shoulder; a strip having slots registering with the slots in said shoulder; a clip longitudinally adjustable within said molding having locking lugs for projection through said slots when the latter are in register and a screw passing through the outer edge wall of the frame and engaging said stripA to move the latter longitudinally to lock the molding in the frame.

In testimony whereof I hereunto set my hand in the presence of two subscribing witnesses.
